Tungsten Copper Metal Injection Molding

Tungsten copper metal injection molding: Because the tungsten copper after sintering machine is relatively difficult, it has high strength and hardness, so the powder metallurgy method can be used to produce parts. In the process of pressing, the products with large diameter and long diameter after sintering will cause deformation and size deviation. Using metal injection molding technology, not only because of the uniform flow filling mold cavity, but also can directly form a complex shape parts.

The basic process is:

1.Select the metal powder and binder to meet the requirement of forming.
2.At a certain temperature, the powder and binder are mixed into a uniform injection molding material.
The density of tungsten copper is 99%, and the content of copper is up to 10%, 15% and 20%. Adopting direct injection molding of tungsten powder,
After degreasing treatment, the relative perfect compact copper tungsten was obtained. However, due to the complex process and high cost, a large number of binders are introduced in the process. If these binders are not completely degreased in the subsequent sintering process, the properties of the materials will be greatly affected.
